Bumping this thread trying to get an answer for a friend in STL who called me about a 2000 X5 that has an inoperative remote and apparently a broken door lock. The lock on the driver's door moves to the lock position, but not to the unlock. Two keys tried, neither works. Autohaus BMW in STL wants $500 to get into the car. Anyone willing to help with the answer here?

Thanks in advance.

Matt
